6.4 Configuring Cluster E-Mail Notification

Novell Cluster Services can automatically send out e-mail messages for certain cluster events like cluster and resource state changes or nodes joining or leaving the cluster.

In order for cluster e-mail notification to work, you must first configure e-mail notification for server health status using NetWare Remote Manager. For instructions on how to do this, go to Configuring E-Mail Notification for Server Health Status in the NetWare Remote Manager Administration Guide.

You can enable or disable e-mail notification for the cluster and specify up to eight administrator e-mail addresses for cluster notification.

IMPORTANT:If you add or delete an administrator e-mail address or change the type of cluster events you want administrators to receive messages for (verbose to XML, etc.), you must reload cma.nlm (the Cluster Management Agent) and perform a cluster join on each node for the changes to take effect. Reloading the cma.nlm on a node causes a cluster migration of all loaded resources on the node to other nodes, and then performs a cluster leave for the node. Loading cma.nlm does not automatically cause the node to rejoin the cluster, so you must issue the cluster join command afterwards. Repeat this for each node in the cluster.

Another way to do this is to unload cma.nlm (the Cluster Management Agent) and run ldncs on each node in the cluster. The ldncs command automatically loads cma.nlm and runs the cluster join command for the node. Repeat this process for each node in the cluster.

Using iManager

  1. In Roles and Tasks, select Clusters, then click the Cluster Options link.

  2. Type the cluster name or browse and select it, then click the Properties button under the cluster name.

  3. Click the General tab.

  4. Select or deselect the Enable Cluster Notification Events check box to enable or disable e-mail notification.

  5. If you enable e-mail notification, add the desired e-mail addresses in the field provided.

    You can click the buttons next to the field to add, delete, or edit e-mail addresses. Repeat this process for each e-mail address you want on the notification list.

  6. If you enable e-mail notification, specify the type of cluster events you want administrators to receive messages for.

    To only receive notification of critical events like a node failure or a resource going comatose, click the Receive Only Critical Events radio button.

    To receive notification of all cluster state changes including critical events, resource state changes, and nodes joining and leaving the cluster, click the Verbose Messages radio button.

    To receive notification of all cluster state changes in XML format, choose the XML Messages option. XML format messages can be interpreted and formatted with a parser that lets you customize the message information for your specific needs.

  7. Click the Apply button to save changes.

Using ConsoleOne

  1. Right-click the cluster object

  2. Click Properties.

  3. On the Cluster Object property page, select the Notification tab.

  4. Select or deselect the Enable Cluster Notification Events check box to enable or disable e-mail notification.

  5. If you enable e-mail notification, add the desired e-mail address in the field provided and click the button next to the field to add the address to the list. Repeat this process for each address you want on the notification list.

    It is not necessary to add quotes to e-mail address names.

  6. If you enable e-mail notification, specify the type of cluster events you want administrators to receive messages for.

    To only receive notification of critical events like a node failure or a resource going comatose, click the Receive Only Critical Events radio button.

    To receive notification of all cluster state changes including critical events, resource state changes, and nodes joining and leaving the cluster, click the Verbose Messages radio button.

    To receive notification of all cluster state changes in XML format, choose the XML Messages option. XML format messages can be interpreted and formatted with a parser that lets you customize the message information for your specific needs.

  7. Click the Apply button to save changes made.

Using Novell Remote Manager

  1. In the left column, select Clustering, then select Cluster Config.
